Manchin has faced some criticism from Democrats at home in the days since his vote. But running in a state President Donald Trump carried by 42 points in 2016, Manchin has to win over Trump voters. He told the Associated Press in an interview in Charleston on Sunday that his vote wasn’t a political decision.

Manchin has led in recent public and private polling of the race. In a Tarrance Group survey conducted for the Senate Leadership Fund Sept. 23-25, Manchin led Morrisey 47 to 43 percent. Manchin’s own polling of the race, conducted Sept. 19-23, gave him a 12-point lead.
